Electrostatic potential is work to bring from reference point over charge¶
Electrostatic potential is a physical quantity defined as the amount of work needed per unit electric charge to move it from a reference point, usually infinity, to a specific point in an electric field.
Infinity is usually used as the reference point because this would make the potential approach zero at an infinitely remote point.
Notes:
The electric potential is defined up to a constant.
